How do I connect the Hydrant valve brass, with STORZ aluminium or brass connection to my fire water supply with external thread?

To connect the Hydrant valve brass, with STORZ aluminium or brass connection to a fire water supply with external thread, follow these steps: 1. Verify thread size (1" to 2Â½") and working pressure compatibility (16 bar). 2. Remove any protective caps and inspect the white NBR seal on the STORZ connection; replace if damaged. 3. Fit an appropriate male-to-STORZ adapter if your supply has external threads: select an adapter whose male threaded end matches your supply thread and whose female end mates with the Hydrant valve brass, with STORZ aluminium or brass connection Format. Use a compatible material (brass/aluminum) to avoid galvanic corrosion. 4. Apply suitable thread sealant or PTFE tape rated for fire-fighting systems to the supplyâs external threads. 5. Screw the adapter onto the supply hand-tight, then tighten with a wrench to specified torque; avoid over-tightening. 6. Engage the Hydrant valveâs STORZ coupling to the adapter and lock per STORZ procedure (rotate and secure). 7. Pressure-test the connection to 16 bar and check for leaks; retighten or reseal as needed. If unsure, consult a qualified fire protection technician.
